Can 3D really make a movie that’s 20 years old worth seeing again? It’s been two decades since Jurassic Park first hit theaters, and since it doesn’t look like we’re getting Jurassic Park 4 any time soon, we might have to settle for this. The original Jurassic Park was a milestone movie – it proved that CGI was the wave of the future in special effects, opening the door for dozens of imitators. Now Steven Spielberg is supervising a 3D conversion – popular in recent movies, but never been tried on a movie this old – and the first trailer just dropped. It’s basically just the original trailer, but in 3D. That’s not a bad thing. Jurassic Park 3D hits theaters on April 5, 2013.
